Sika Sikacim Pink — Integral Liquid Waterproofing Admixture for Concrete & Mortar (20 Ltr)

Surface waterproofing has its place, but it works on a slab or wall after the concrete is already cast — sealing from the outside, exposed to weather, foot traffic and eventual wear. The more durable approach is to build water resistance into the concrete or mortar itself, at the mixing stage, so the matrix that carries the load is the same matrix that resists water ingress. That's the role an integral liquid waterproofing admixture is designed to play, and it's the reason Sikacim Pink from Sika India Pvt. Ltd. has earned its place as a standard addition to waterproofing mixes on sites across India.

Sikacim Pink is dosed directly into the gauging water during concrete or mortar mixing. It works by reducing capillary water absorption inside the cured matrix — the same micro-channels that normally let water creep through a slab, plaster coat or external rendering are tightened up at the chemistry level, so the finished surface holds water out rather than wicking it in. The pink tint also gives applicators an immediate visual confirmation that the admixture has actually been added to the batch, which matters on sites where multiple mixes are running through the day and dosing errors are easy to make without a colour cue.

The product is widely reached for in roof slab concreting, terrace screeds, bathroom and toilet sunk slabs, external plaster on walls exposed to rain, water tank construction and basement work — applications where waterproofing failure isn't easy or cheap to correct after the fact. Contractors trust it because the dosing is straightforward, it's compatible with standard OPC and PPC cement, and it doesn't demand a change to the existing mix design or workflow. The result is a concrete or mortar layer that carries water resistance internally rather than depending entirely on a coating applied later.

A construction chemical from Sika India Pvt. Ltd. that addresses waterproofing where it's most effective — inside the mix, not on top of it. Sikacim Pink is the integral admixture specification for projects where long-term resistance to seepage and dampness needs to be designed in from the first pour.
